I don’t think this is a major “this is why people pirate”. Pirate sites also regularly get cracked (possibly more often the the average streaming service). It isn’t like bank details were leaked here so the only real difference is that in some pirate sites you don’t need a login at all.
Who logs into a pirate site, though? Who gives them their financial information?
As a crunchyroll subscriber, this fucking sucks. They are not doing their jobs.
Crunchyroll came from piracy, never felt right paying for it
Sony and getting hacked, name a more iconic duo
Unclear whether they were hacked. A followup says:
We [Crunchyroll] have […] investigated the situation, and determined that there is no evidence that Crunchyroll’s systems have been compromised
They may have been fished.
